A man who police said was involved in a fatal car crash on Route 22 in October has now been charged with homicide by vehicle while driving under the influence.

The case docket indicates that 43-year-old David Brown McCormick is charged with DUI at the highest rate of alcohol, which means a blood-alcohol content of 0.16 percent or above. The legal limit for a Pennsylvania driver is 0.08 percent.

McCormick, of the 15212 ZIP code, is awaiting his preliminary hearing before District Judge Charles Conway.

The victim was identified as Francis G. Cossick, 66, of Camp Hill, Pa., near Harrisburg. His wife and son were said to be in a second car just ahead of him on the night Oct. 9.

"They knew what was happening, and I think they saw some things, but I don't know to what extent," Murrysville Police Chief Thomas Seefeld said in October. "Fortunately, we used our police chaplain to deal with the family on that side of it. But, absolutely hard to deal with."

The Westmoreland County Coroner's Office said Cossick was driving east on Route 22 (William Penn Highway) at about 10:41 p.m. As he neared Mellon Road, a car hit the back of his vehicle, smashing in almost the entire rear end.

An autopsy found that Cossick died from multiple blunt-force injuries to the chest and abdomen.

"Speed is believed to have played a factor," a deputy coroner wrote in a media report.
